If the thread were drawn straight from the needle across. the tongue, itwould be very liable to catch therein, and it would be diffi cult to getit out. Theflare between the left handside of the. tongue and thepresser foot keeping it. from catching there, and at the I presser footunder any desired thickness of claim as new and desire to secure by Let-",tersPatent, is

,"j-the fabric, a presser foot having a recess 10- Q -cated in the pathof travel of said thread body, forces the thread along on the tongue 1as it is drawn taut, and this has the effect of dra it out of theV-shaped slot. Were it not or the fact that the left hand side'of :10

the tongue of the presser foot is made upon the peculiar curve startingat a point opposite the needle, the thread would catch in thev-v'shapedfs'lot, and would not come out, but the, drawing of the threadover. a point higher than the'sides of the V slot has the effect of.s'ame tlme, allows the looper in its travel to pass over the side ofthe presser foot, without en agin with it. a

4 t wilIbe understood that I do not wish to be limitedto the exactdetails of construction, the essentials of the invention being that thepresser foot has the notched tongue,

or the notch adjacent the tongue, so that the looper has sufiicientclearance over the -fgo0ds; and also that the notchis so formed that thethread will not catch in the notch but will slip over it onto thetongue.

Having thus described my invention, what 1.111 a sewing machine having-stitch forming mechanism including a device for laying a thread uponthe upper surface of laying device, 'andupon the top side of the bearingsurface of said, f ot, saidrecess being so arranged as that threadwillbe deflected out of it; substa... slly as described.
